Abstract

The invention provides a longitudinal baffle plate type heat exchanger. The longitudinal baffle plate type heat exchanger comprises a shell, a tube plate and a tube bundle; the tube bundle is arrangedin the shell through the tube plate, the longitudinal baffle plate type heat exchanger further comprises a mesh type supporting plate, the mesh type supporting plate is arranged in the shell, multiple limiting holes for inserting of the tube bundle and multiple circulation holes communicating with the two sides of the mesh type supporting plate are formed in the mesh type supporting plate, and the tube bundle is inserted on the limiting holes. Through the technical scheme, through the mesh type supporting plate, the tube bundle is fixed, the whole fixing effectiveness is good, vibration and deforming of the tube bundle in the use process can be avoided, in addition, the circulation holes are formed in the mesh type supporting plate and can communicate with the two sides of the mesh type supporting plate, the normal running of shell side media within the tube length range of the tune bundle can be facilitated, therefore, the mesh type supporting plate can transversely support the tubebundle, flowing of the shell side media is not affected, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a longitudinal baffle heat exchanger. Background technique [0002] Shell-and-tube heat exchangers are commonly used equipment in chemical plants. Longitudinal baffle heat exchangers are a form of shell-and-tube heat exchangers. They have special applications in corresponding process devices. They have the advantages of high flow rate and low pressure drop. features. [0003] As we all know, the shell-and-tube heat exchanger tube bundle structurally requires a lateral support structure to increase the rigidity of the tube bundle or eliminate the vibration of the tube bundle. If a small-volume transverse support structure is used, the manufacturing effect is poor, and it is difficult to eliminate the vibration of the tube bundle; if a large-volume transverse support structure is adopted, it will hinder the normal flow of the shell-side medium along the entire length of...
